The effectiveness of non-pharmacological treatment on gait impairment on Parkinson Disease (PD) such as exercises has been demonstrated; in particular an example for patient tailored exercises is physiotherapy. The goal of physiotherapy treatment is to enable PD patients to maintain their maximum level of mobility, activity, and independence. Several systematic reviews and clinical studies have shown that physical therapy can contribute to minimize the disabling effects of motor and sensory impairments in order to enhance participation in societal roles and quality of life. The use of electromechanical devices such as treadmill training (a supplement to conventional therapies) in the last years has also been used with PD patients and a systematic Cochrane has been conducted by Mehrholz in 2010 to assess the effectiveness and acceptability of treadmill training in the treatment of gait disorders for patients with PD. In the last years new robotic assisted device can be used in gait training in neurological disorder. Till now only few studies, have focused on the effects of exoskeleton or end effector robot-assisted training in PD patients, with a interesting preliminary results.

The 6 minuts walking test as primary outcome assessments will be collected 1 hour after oral assumption of levodopa at baseline (inclusion)(T0) and endpoint (after 20 robot sesion) (T1) (no later than 1 day > last training session) at the follow-up examination after 6 months from the treatments conclusion (T2).

Time Up and Go test will be collected 1 hour after oral assumption of levodopa at baseline (inclusion)(T0) and endpoint (after 20 robot sesion) (T1) (no later than 1 day > last training session) at the follow-up examination after 6 months from the treatments conclusion (T2).

Gait Analysis will be collected 1 hour after oral assumption of levodopa at baseline (inclusion)(T0) and endpoint (after 20 robot sesion) (T1) (no later than 1 day > last training session) at the follow-up examination after 6 months from the treatments conclusion (T2).

Group A (GA) of subjects (at least 40 subjects) will undergo inpatient rehabilitation consisting of a treatment cycle using the GE-O system device, according to individually tailored exercise scheduling. The practice will include robot-assisted walking at variable speeds for 45 min with a partial body weight support (BWS). All participants started with 30-40% BWS and an initial treadmill speed of 1.5 km/h speed will be increased to a range of 2.2 to 2.5 km/h before BWS will be decreased.

Detailed Description:

The specific aims of this project are:

to verify whether the robotics lower limb treatment with body weight support is more effective than the treadmill treatment in the reduction of motor impairment in PD or PSP patients, and to improve the quality of the gait and the endurance;

to analyze possible improvements in terms of physiological biomechanical gait through analysis of kinematics , kinetics and EMG evaluation;

to analyze possible improvements in terms of reduction of instable posture and movements , which can represent a reduction of the risk of fall typical of these subjects;

to investigate the stability of the effects of robot-assisted treatment at 4/6 months follow-up in terms of Quality of Life (QoL).

A first goal of this project is to investigate the differences in improvement of the quality and safety of the gait (motor performance and functional recovery) through kinematic/kinetic and EMG parameters (Change in Step Length, Change in Gait Velocity and Change in Stride Time Variability, 3D joints kinematics, ground reaction forces, joint kinetics, muscle activation,) and traditional clinical scales in Parkinson's patients.

The second goals is aimed at identifying possible advantages in the QoL of patients undergoing such a kind of rehabilitation treatment and at investigating novel methods enabling lower limb functional recovery, leading to wide potential for regaining personal independence.

The third goal is to analyze direct cost savings associated with the use of such technologies, measured as direct, indirect and intangible costs, through specific HTA procedures.
